Can be called as Sel_Action userexit at any mask where records can be selected or scrolled.
The userexit is especially useful for the record-dependent display of images in forms. To do so, a separate data field must be defined to hold the corresponding image file name using the syntax: #filename. The userexit will then output the image file in the field title at the trigger moment.
